    Microstructure of Ti-6Al-4V produced by selective laser melting by Marco Simonelli, Yau Tse, Christopher Tuck

    Published 2012
    “…The starting material, a plasma atomised powder, and the component products are studied using various microscopy techniques including optical, scanning electron and transmission electron microscopy and electron backscattered diffraction (EBSD). Powder particles are fully dense, possess a spherical shape and are composed of acicular α phase. …”

    Effect of the build orientation on the mechanical properties and fracture modes of SLM Ti–6Al–4V by Marco Simonelli, Yau Tse, Christopher Tuck

    Published 2014
    “…Fractography and electron backscatter diffraction (EBSD) results indicate that the predominant fracture mechanism is intergranular fracture present along the grain boundaries and thus provide and explain the typical fracture surface features observed in fracture AM Ti–6Al–4V.…”

    The influence of iron in minimizing the microstructural anisotropy of Ti-6Al-4V produced by laser powder-bed fusion by Marco Simonelli, David Graham McCartney, Pere Barriobero-Vila, Nesma T Aboulkhair, Yau Tse, Adam Clare, Richard Hague

    Published 2020
    “…The operating mechanisms that govern the relationship between the alloy composition (and Fe in particular) and the grain size are explored using EBSD, TEM, and in situ high-energy synchrotron X-ray diffraction. It was found that Fe additions up to 3 wt pct lead to a progressive refinement of the microstructure. …”

    On the texture-formation of selective laser-melted Ti-6Al-4V by Marco Simonelli, Yau Tse, Christopher Tuck

    Published 2014
    “…Phase and texture analysis were carried out using backscattered electron imaging and diffraction. It was found that as-built components consist exclusively of α martensitic phase precipitated from prior β columnar grains. …”
